To create the images above i followed the same guide as for my 'holding a planet' image. I simply removed the back ground from the city image on Photoshop using the quick selection tool, pressed Ctrl>alt>T to re-size the building, then used the eraser to erase the excess parts of the building where the hands are. However making sure only the building layer is selected. i then added a black and white layer effect to one of the images to create a different look.

Holding a planet

To create this surreal image i simply removed the back ground from the tiny planet on Photoshop using the quick selection tool, pressed Ctrl>alt>T to re-size the planet, then used the eraser to erase the excess parts of the planet where the hands are. However making sure only the planet layer is selected.
